Both Premier League sides are eyeing a move for the striker, who is only contracted to the Bundesliga side until 2014, but Arnesen believes the South Korean can become one of the club’s most valued players.‘He is a real poacher. Chance, boom, goal,’ the Dane told Hamburger Abendblatt.‘He is one of our key players for the future. Our pain barrier concerning Son is gigantic. We do not want to give away players who make us better, under no circumstances.’Son has made a flying start to the current campaign, scoring six goals in 13 appearances for Hamburg.But despite his form attracting interest from around Europe, the 20-year-old says he is keen to remain at the Imtech Arena.‘(I feel) very, very comfortable (at Hamburg). The city is amazing and the fans are really terrific,’ Son said.‘I still have a contract until 2014 and I have to talk about it with my dad and my agent.’
